ABSTRACT
Objective: To investigate the characteristics of air-conducted sound cervical vestibular evoked myogenic potential ï¼ACS-cVEMPï¼ and bone-conducted vibration cervical vestibular evoked myogenic potential ï¼BCV-cVEMPï¼ in healthy preschool children, and to provide the normal reference range of VEMP for preschool children in China. Methods:Forty-four normal-hearing children ï¼88 earsï¼ aged 3-7 years were recruited to undergo ACS-cVEMP and BCV-cVEMP determination. These children were divided into two groups according to age: 3-4 years old group ï¼ 17 cases, 34 earsï¼ and 5-7 years old group ï¼ 27 cases, 54 earsï¼. The response rates and waveform parameters were recorded and analyzed statistically using SPSS 18.0 software. Results:The response rates of ACS-cVEMP, BCV-cVEMP in 44 normal-hearing children ï¼88 earsï¼ were 96.59ï¼ ï¼85/88ï¼ and 97.73ï¼ ï¼86/88ï¼ respectively, and there was no significant difference between the two groups ï¼P > 0.05ï¼. The response rates of ACS-cVEMP in 3-4 year old group and 5-7 year old group were 94.12% ï¼32/34ï¼ and 98.15% ï¼53/54ï¼ respectively, and there was no significant difference between the two groupsï¼P>0.05ï¼; The response rates of BCV-cVEMP in 3-4 year old group and 5-7 year old group were 94.12% ï¼32/34ï¼ and 100.00%ï¼54/54ï¼ respectively, and there was no significant difference between the two groups ï¼P>0.05ï¼. Compared with the 5-7 year old group, the latency of p1 and n1 in the 3-4 year old group was shorter ï¼P<0.05ï¼ and the amplitude was higher ï¼P<0.05ï¼, and there was no significant difference in other parameters ï¼P>0.05ï¼. There was no statistical difference in threshold, n1, p1 latency, n1-p1 wave interval, n1-p1 amplitude, and amplitude asymmetry ratio of BCV-cVEMP between the two groups ï¼P>0.05ï¼. Conclusion:ACS-cVEMP and BCV-cVEMP can be elicited in most preschool children, and cVEMP is a feasible method to detect vestibular function in children.

Vestibular dysfunction, which may lead to delayed motor development and reduced quality of life, is an overlooked entity among children and adolescents. Vestibular evoked myogenic potential ï¼VEMPsï¼ is a common, safe diagnostic tool in adults for vestibular disorders. However, there is no related data for children and adolescents. We aimed to collect and assess normative VEMP data for adolescents. In this article , we analyzed the results of VEMPs in children in recent years, and summarized the common detection methods of VEMPs in children, the detection rate and variability characteristics of VEMPs in children of different ages, and the current status of clinical application of VEMPs in children.
